SHUTTLE FOR CONTINUOUS WEFT-LOOMS.

Specification ofLetter's Patent. Patented Feb, 13, 1917.

Original application filed October 27, 1915, Serial No. 58,190. Divided and this application filed October 24.

V 1916. Serial No. 127,465.

To all whom it may concern:

Be it known that I, ALBERT SMITH, a subject of the King of Great Britain, and resident of No. 31 Treaford Lane, Ward End, Birmingham, England, have invented cer-. tain new and useful Improvements in Shuttles for Continuous "Weft-Looms, of which the following is a specification.

This invention is a division of that disclosed in my application filedv October 27,

1915, Serial No. 58,190, for looms for weaving, and is an improved construction of shuttles for continuous weft looms, whereby the yarn is permitted to enter and leave the shuttle on its front face, that is, the face presented to the fell of the cloth in the continuous feeding of the weft into the fabric.

I will describe the improvements constituting my invention in connection with the accompanying drawing.

Figure 1 represents in front elevation, Fig. 2 in plan and Fig. 3 in cross section the new or improved shuttle hereinafter described.

Figs. 4 to 7 both inclusive illustrate a modification of the new or improved shuttle also hereinafter described.

The same letters of reference indicate the same parts in the several figures of the drawing.

a is the shuttle having the longitudinal slots b, c in its front face and a vertical longitudinal slot (1 parallel or approximately parallel with the front face and extending from the upper to the underside of the shuttle as is best seen in Figs. 2 and 3.

In threading the shuttle the weft thread is passed through the slot 7) in the front face of the shuttle into the vertical slot (1 and from the inner side of the said vertical slot d back through the slot 0 the end of the thread being fastened to the selvage or outside warp thread at the side of the loom from which the shuttle is first thrown.

As will be seen by reference to Fig. l'the longitudinal slots 6, c in the shuttle a terminate one in advance of the other near one end of the shuttle, and are so shaped or curved at the said end that the two strands or shots of weft are brought together, or side by side, when the shuttle is at one side of the loom.

, -On the shuttle being thrown from the shuttle box at the side of the loom from which the weaving is commenced the shuttle takes the weft therewith and a double pick of weft is thereby inserted in the cloth, the weft being drawn to the opposite or straight ends of the slots 6, 0, the double pick of weft presenting an open triangle as 15 indicated in dotted lines in Fig. 1 when the shuttle enters the shuttle box at the said other side of the loom. The open triangular loop in the weft is on the beat up of the slay brought over a weft retaining device such as is described and represented in the specification of my pending U. S. patent application Serial No. 58,190. The weft is held by the weft retaining device on the return motion of the shuttle.

I wish it to be understood that I do not limit myself to the exact construction hereinbefore described and illustrated of my new or improved shuttle as the same may be varied without departing from my invention, and in Figs. 4 to 7 both inclusive I have represented the said new or improved shuttle somewhat modified in construction.

Fig. 4 represents the said modified shuttle in front elevation and Fig. 5 is a plan of the same.

Figs. 6 and 7 are cross sections taken on the dotted lines m-w and y-3 respectively of Fig. 4:.

According to this modification theshuttle a has holes 6, e made in its front face at a short distance from each end. The holes e may be upwardly inclined so as to open on the top or upper face of the shuttle near'the back edge thereof, or the said holes 6 may be horizontal and open into vertical recesses f in the top or upper surface of the shuttle as is illustrated in Figs. 5 and 7. In the top or upper face of the shuttle extending from one recess f to the other is a longitudinal groove or channel 9 and in the front face of the shuttle between the holes 6, e is a recess h. The front face of the shuttle also has in .it shallow grooves z.

- The weft is threaded through the left hand hole 6 in the front face of the shuttle a and up through the hole fat the said end. It is then passed through the hole f near the right hand end of the shuttle and emerges on the front face through the right hand hole e. The part of the weft thread between the two holes I, f is made to occupy the guiding groove 9.

From the description hereinbefore given it will be understood that the weft in pass- 110 ing through the shuttle enters and emerges from the front face of theshuttle, thereby permitting the weft to be drawn continuously through the shuttle.

The loose end of the weft is. before starting fastened to the selvage at the side from whichthe weaving is commenced as in'the first described arrangement.

Having described my invention what I claim as new and desire to secure by Letters Patent is I 1. A shuttle for continuous weft looms comprisingqavshuttle body of suitable form provided with two yarn guiding openings in the front face, that is to say, in the face presented to the fell ofthe cloth, which yarn guiding openings allow the yarn to enter and emerge from the shuttle on the said front face whereby the yarn is permitted to pass continuously through the shuttle.

2. A shuttle for continuous weft looms having in its front face two longitudinal parallel slots, one terminating at one end nearer the tip of the shut-tle'than the other same horizontal plane, the other ends of the slots terminating in horizontal planes referably situated as far apart as is admitted other within the body of the shuttle, and being divergent on the face of the shuttle, whereby a loop of yarn entering one aper ture and passing out through the other will be drawn together when the shuttle is thrown in one direction and will be held open when it is thrown in the other direction. In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.
